Abstract
A method of forming a solder joint between a cup shaped high voltage terminal and a secondary lead extending from a secondary coil within a plastic case of an ignition coil. The steps include securing a solder paste to an inwardly extending end of the high voltage terminal, positioning the secondary coil lead relative to the solder paste, and heating the joint without making physical contact therewith to promote melting of the solder to secure and electrically connect the desired components.
